Car - 05 reg, 1.6tdci, 88k miles, owned from "nearly new"

I've looked through this very useful forum and may others in relation to turbo, MAF, MAP, EGR issues on the 1.6tdci and have read about all the problems identifying and fixing etc

Anyway, I am getting the "engine system fault" message and managed to get my local independent garage whicj me and my wife use to have a look at it at short notice eventhough they were busy. They haven't managed to fix the problem but reported that the error code(s) were to do with "too much overboost" and have done the usual checing of pipes etc.

They have advised me to bring the car back in about a weeks time when their "diagnostic/electrical" specialist is back from holiday so that he can have a proper look at it,

Over the weekend armed with some knowledge gained from forums, a purchased Haynes manual I went about checking the engine over my self and:

1. changed the dirty air filter
2. clean the MAF sensor - there was some oil on the inside of the casing
3. added some Wynns injector cleaner
4. disconnected the battery overnight

On road testing, the car seems to be as smooth as before running through the gears without overloading until I'm hitting 50-60mph when I "floor it" to get bit of boost for overtaking etc ie. fault message/limp mode.

On further inspection and reading about the MAP sensor on the intake manifold, I have notice what looks like a missing cover near the MAP sensor (image link) - could this be the cause of the overboost problem?


This is very annoying since the car was running really nicely (too nice?) since I had the timing belt changed about 1 month ago.

Any help much appreciated, especially since this is my first post.

Ahh, I see the problem here, that it's not a Ford engine!

Is that an open hole on the air intake pipe? If so, you better cover it up as dust and dirt will be sucked in and destroy your turbo and/or engine.
